FEATool Heat Transfer Verification of a Multi-PCM Passive Vaccine Cold Chain Container
How long can a vaccine container stay cool without electricity? Researchers at the Technological Institute of the Philippines investigated a passive container designed to maintain a vaccine compartment between 2 and 8 °C for 17 days in a constant 35 °C environment. The design combines vacuum insulation with phase …
Aortic Valve Stress and Strain Simulation with FEATool Multiphysics
Finite Element Analysis (FEA) of the aortic valve can be used to predict leaflet stress, strain, and deformation throughout the cardiac cycle. This is particularly relevant for congenital valve variants such as bicuspid and quadricuspid aortic valves, where altered leaflet geometry can produce asymmetric mechanical …
Structural mechanics FEA simulation for design of Push-Pull robots
This paper explores the design of “concentric push-pull robots” designed to make endoscopic surgery easier, such as biopsies or to removing polyps. In contrast to using colonoscopes which are difficult to maneuver, and may lead to longer procedure times and a higher chance of needing additional more …
Thrombosis risk assesment with FEATool Multiphysics CFD simulation using PIV data
The following research, conducted by Borowski F., Kaule S., and colleagues concerns a type of heart valve that can be inserted without open-heart surgery (transcatheter aortic valve replacement TAVR). The researchers wanted to see if the way the valve is inserted affects how well blood flows through it, specifically …
Simulation of Heating to Promote Drug Mixing in the Eye
The leading cause of central vision loss in the developed world is from age-related macular degeneration (AMD). Although certain types of AMD can generally be managed with injections of anti-VEGF agents, the treatment is sometimes ineffective. The linked study examines how this type of treatment potentially can be …
